Five Star Service!
I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs
Best Truck I ever owned!
This truck is everything I wanted! GMC, 4x4, Lifted, Low milage. It's going to be great for my hunting and 4 wheeling! I love it!

Kyi at Castle Rock Chevrolet is the best in the business.
Kyi at Castle Rock Chevrolet is the best in the business. If I could give more than 5 stars I would. I came to Castle Rock Chevrolet from Montana carrying the weight of a terrible deal I’d been locked into by Mike Maroone Chevrolet. I was horribly upside down on my previous vehicle, thanks to a deal that should never have been approved in the first place. It felt hopeless… until I connected with Kyi. Kyi didn’t just help — he changed everything. He took the time to understand my situation, walked me through every option with honesty and clarity, and treated me like a person, not a number. Thanks to his determination, professionalism, and integrity, I am now driving a 2017 Cadillac Escalade Premium Luxury — a vehicle I absolutely love, and a deal that finally makes sense for me and my family. What makes this even more impressive is that we did the entire deal remotely from Montana. Kyi made it unbelievably easy and stress-free — constant communication, no surprises, and everything was handled with total transparency. It was hands down the most respectful and seamless car-buying experience I’ve ever had. I also want to give credit to Luke, the desk manager, who was the one that made the numbers work. He took a tough situation and made the deal make sense — without cutting corners or playing games. It was clear he genuinely wanted to help, and I’m incredibly grateful for the effort he put in behind the scenes. Kyi and Luke are the kind of team members who elevate the entire Castle Rock Chevrolet experience. People from any state should be buying their cars here. I would do it all over again in a heartbeat. If you’re buying a car from Castle Rock Chevrolet, do yourself a favor — ask for Kyi. You’ll be glad you did. Thank you both — you’ve earned customers for life.
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Great car buying experience. Friendly, knowledgeable, no pressure salesman Kyle Berry. One minor problem was handled quickly and professionally with no hassle. Go see Kyle.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

We arrived less than 60 mins before closing on a holiday. We were super impressed and we went home with a new car. It was after closing and more than one person was still there working. You don?t see that these days. Our car salesman even took a selfie with us.

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Found a desk area with electrical outlet the chairs were kind of old and banged up, and it was kind of in the vending area. Wi-Fi was good for working, but the coffee area was all out of packets for coffee. Good service and they got me out quickly through the process for an oil change the first one on my vehicle and the first service at that location. It was good the The cut customer service was good
